Abstract
BACKGROUND: Refractive errors (REs) are the major cause of blindness and impaired vision with considerable morbidity. Finding the prevalence with early detection of REs with appropriate corrective measures can bring down eye morbidity in children. AIM: The aim of the study was to find the prevalence of REs among children attending Raichur Institute of Medical Sciences Teaching Hospital in Karnataka State of South India. METHODOLOGY: This hospital-based cross-sectional study was conducted with a total of 420 study subjects. Examination of the eyes for REs was carried out using a refractometer. The REs were noted in myopia < -0.5 dioptres (D), hypermetropia > + 0.5 D, and astigmatism > 0.5 cylinder D. The data were statistically subjected to a statistics test. Categorical measurement was presented as frequency (percentage). The association between the parameters was done using the chi-square test. A p-value < 0.05 was considered statistically significant. RESULTS: Out of 420 examined, REs were present among 147 (35%) study subjects, and myopia 67 (16%) was the highest prevalent in comparison to hypermetropia 42 (10%) and astigmatism 38 (9%). The male subjects had 77 (34.4%) REs, and the female subjects had 70 (35.7%) REs. In both genders, myopia was the highest prevalent, followed by hypermetropia and astigmatism. CONCLUSION: The prevalence of REs among children is alarming, and it should be corrected at an early age to prevent further complications in adulthood. Ophthalmologists should generate regional data about the prevalence of REs, create awareness about the prevention of REs among the risk population, and utilize government-sponsored blind eradication programs for comprehensive eye care in the larger interest of the affected population and risk population.
